Which of the following statements is not true?

Options

AChain growth polymerisation involves homopoly-merisation only
BChain growth polymerisation includes both homo-polymerisation and copolymerisation
CNylon 6 is an example of step-growth polymerisation
DStep growth polymerisation requires a bifunctional monomer

Correct answer

B. Chain growth polymerisation includes both homo-polymerisation and copolymerisation

Step-by-step solution

The statement (b) is not true. Chain growth polymerisation (or addition polymerisation) involves homopolymerisation only Examples of such polymers include polythene, orlon and teflon.
